An ophthalmo-phantom is a teaching device allowing students to practice, to train, in eye surgery. The metal mask was mounted on a height-adjustable and tilting stand. A device fixed behind the mask allowed a real eye (often pig or rabbit) to be introduced into the orbit and the student could then practice the desired operation.
